My most favourite place to eat at in Sydney is Kashiwa Yakiniku at Crows Nest. It’s a fairly affordable Japanese wagyu bbq, with the meat plates around the $10-$12 mark.
It’s a simple meal but so amaze. Service at the place is negligible, but the meat does come out fast. I think it’s because they want you out of there quickly to make room for more customers.
My brother and I ate 5 serves of meat within the one hour time limit they gave us. We felt very accomplished after.
